MAGNUS GROSS, OF NEWV YORK, N. Y.

APPARATUS FOR MANUFACTURING GAS.

SPECIFICATION forming part of Letters Patent No. 392,555, dated November 6. 1888.

Application filed December 1'7, 1887. Serial No. 258,248. (No model.)

To all whom it may concern:

Be it known that I, MAGNUS GRoss, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Mannfacturing Gas; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for manufacturing gas.

The object is to present a new and improved mantle or jacket to prevent the loss of heat from the pipes distributing heated fluid or fluids.

The invention consists of a mantle, jacket, or hood made of sheets of metal with a narrow space between them, to be attached to the masonry of a bench of retorts in such manner as to form a chamber.

Furthermore, the invention consists in various parts and details and combinations of the same, as hereinafter more fully described.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, Figure l is an end elevation of a bench of retorts with my improvements applied, parts being broken out. Fig. 2 is a sectional side elevation of the same on the lines as as of Fig. 1. Fig. 3 is a sectional plan view of the same on the lines yy of Fig. 1.

On the rear end of a bench of gasmaking retorts,A,is held a mantle, jacket, or hood, B, which forms a chamber, 0, on the rear end of the bench A. The latter is preferably made in sections jointed together and interlocking in a suitable manner to permit access to the superheater and the distributing-pipes located in the chamber. The joints are well cemented to close seams and fissures and pre vent the escape of heat and the entrance of air into the chamber. Each section is made any other highly-polished metal.

E are to form the air-spacesG between the outer and inner plates, D and F. On the ends of the plates D and F are secured the flanges H, which fit with their outer edges into the corresponding grooves, I, formed in the masonry at the rear end of the bench A.

The mantle, jacket, or hood thus constructed' prevents to a great extent any loss of heat from the chamber 0, thus preserving the high temperature of the superheated steam or other fluid passing through the distributing-pipes located in the said chamber and permitting easy access to these pipes and to the superheater. The inner plate, D, is made of sheetiron of sufficient thickness to resist the action of low-red heat and the airspace between it and the outer plate lessens the capacity of heat passing from it. The outer plate, F, being made of sheettin or sheet-copper, or other highly-polished sheet-metal, is thus to add to the poor heat-conductor already provided for. In this manner very little heat is perimittedto escape from the chamber 0.

The mantle, jacket, or hood, furthermore, is constructed in such a way that the heads of the mouth-pieces J, attached to the rear ends of the retorts, pass through it by several inches to allow the introduction of oil-supply pipes outside of the heated chamber.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combinatiomwith a bench of retorts, of'a mantle, jacket, or hood held in the ma sonry on the rear end of said bench and forming a chamber between the face of the bench and the said mantle, jacket, or hood, the said chamber containing the distributing-pipes for the superheated steam, substantially as shown and described.

2. The combination, with a bench of retorts. ofa mantle, jacket, or hood, the masonry of the rear end of the bench provided with grooves and the inner plate of the mantle, jacket, or hood with flanges to fit into the grooves, and thereby form the chamber, substantially as shown and described.
